General Description

Demultiplexed address and data buses

Multiplexed DRAM address bus (NS32FX200 and

NS32FV100)

The NS32FX200, NS32FV100 and NS32FX100 are highly

integrated system chips designed for a FAX system based

on National Semiconductor’s embedded processorsÐ

NS32FX161, NS32FV16 or NS32FX164. The NS32FX100 is

the common core for all three system chips. The

NS32FV100 and NS32FX200 offer additional functions.

Throughout this document, references to the NS32FX100

also apply to both the NS32FV100 and the NS32FX200.

Specific NS32FV100 or NS32FX200 features are explicitly

indicated.

Supports 3V freeze mode by maintaining only elapsed

time counter

Control of power consumption by disabling inactive

modules and reducing the clock frequency

Operating frequency

Ð Normal mode: 19.6608 MHzÐ24.576 MHz in steps

of 1.2288 MHz. (NS32FX200)

Ð Normal mode: 19.6608 MHzÐ24.576 MHz in steps

of 1.2288 MHz. (NS32FV100)

Ð Normal mode: 14.7456 MHzÐ19.6608 MHz in steps

of 1.2288 MHz. (NS32FX100)

Ð Power Save mode: Normal mode frequency divided

by sixteen

The NS32FX200, NS32FV100 and NS32FX100 feature an

interface to devices like stepper motors, printers and scan-

ners, a Sigma-Delta CODEC, an elapsed-time counter, a

DMA controller, an interrupt controller, and a UART.

The NS32FX200 is optimized for high-end FAX applications,

such as plain-paper FAX and multifunctional peripherals.

The NS32FX100, is optimized for low-cost FAX applica-

tions. The NS32FV100 is optimized for thermal paper FAX

machines with Digital Answering Machine support.

On-Chip full duplex Sigma-Delta CODEC with:

Ð Total harmonic distortion better than 70 dB

Ð Programmable hybrid balance filter

Ð Programmable reception and transmission filters

Ð Programmable gain control

Features

On-Chip Interrupt Control Unit with:

Ð 16 interrupt sources

Ð Programmable triggering mode

On-Chip counters, WATCHDOG^TM, UART,

MICROWIRE^TM, System Clock Generator, and I/O

ports

Direct interface to the NS32FX161, NS32FV16 and

NS32FX164 embedded processors

Supports a variety of Contact Image Sensor (CIS) and

Charge Coupled Device (CCD) scanners

Direct interface to

a variety of Thermal Print Head

(TPH) printers. Bitmap shifter and DMA channels facili-

tate the connection of other types of printers

Supports two stepper motors

On-Chip DMA controller (NS32FX200Ðfour channels,

NS32FX100, NS32FV100Ðthree channels)

Up to 37 on-chip general purpose I/O pins, expandable

externally

Direct interface to ROM and SRAM. The NS32FX200

and NS32FV100, in addition, interface to DRAM

devices

Flexible allocation of I/O and modules’ pins

132-pin JEDEC PQFP package
